We obtained an optical spectrum of AT2017hcc on 2017 October 7.4 with FLOYDS mounted on the FTS 2m at the Siding Spring Observatory. The spectrum shows a relatively blue continuum with one strong, resolved emission line at 6676.3 Angstrom with FWHM~44 Angstrom (~2000 km/s). Assuming that this line is likely Halpha, then AT2017hcc is likely a Type IIn SN at z=0.0173.

We obtained an optical spectrum of SN2017hce on UT 2017 Oct. 25.1 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum is that of a normal Type Ia after peak. SNID (Blondin & Tonry 2007) gives an average epoch of 13.5 days after peak and redshift from SN features of z=0.032 +/- 0.002.
